Testing and Troubleshooting
STEP 1: CHECK THE POWER
Ensure that the red POWER LED is lit (see Figure 9). If
not, check your power connections and/or source. Voltage
reading should be within the range of 9VDC – 18VDC.
STEP 2: CHECK FOR RECEIVER OPERATION
The SIGNAL LED (refer to Figure 9) should be flickering
continuously, indicating that the RF receiver circuitry is
operating.
STEP 3: TEST THE TRANSMITTER/RECEIVER
Press the transmitter button previously set in step 4, page
3, within view of the receiver. If the DATA-yellow and
VALID-green LEDs do not light, review the
Connect Signal/Power Wires
sections.
If the DATA-yellow and VALID-green LEDs
flash repeatedly and simultaneously, the
format settings may be incorrect (refer to
If reception of the transmitter’s signal is significantly
reduced, there may be strong RF interference from other
sources. Common sources of interference include
fluorescent lights, neon signs, mercury vapor lamps, arc
welders, and arcing power lines. Interference due to
lighting can be limited by having an electrician wire a
noise suppressor into the lamp, light, or sign circuit.
NOTE:
It may be required to press the transmitter
button twice at first use.
RECEIVER LED REFERENCE
(Refer to Figure 9.)
SIGNAL – Red
This LED, when lit, indicates that the receiver has
detected the presence of RF energy. It is normal for this
LED to flicker continuously while the receiver is powered
up.
DATA – Yellow
This LED indicates that the receiver recognizes the
transmission data as coming from a Chamberlain®
transmitter with Passport technology.
VALID – Green
This LED indicates that the receiver is sending a
Wiegand format output to the access control system.
POWER – Red
This LED indicates that the receiver has power.
GRANTED – Green
This LED indicates that the access control system has
validated the transmitted code and has granted access.
STEP 4: ATTACH THE FRONT COVER
Attach front cover of receiver by turning screws clockwise
1/4 turn. Do not overtighten.
